A server monitoring software 🌡 named Supermicro SuperDoctor 5 has been encountered during an assessment.
However, @bak_sec and @_mabote_ were not big fans of the web app UX and thought a root shell would be more suitable 🐚

In no time, the mighty @elvanderb pwned his favorite target: XNU, the Apple MacOS kernel! Rumor has it that he took more time developing the ASCII art than the actual exploit 🥷 #P2OVancouver
Success! @Synacktiv used a TOCTOU bug to escalate privileges on Apple macOS. They earn $40,000 and 4 Master of Pwn points. #Pwn2Own #P2OVancouver

A few months ago, we reported a pre-auth Remote Code Execution #RCE vulnerability to @vBulletin. The exploitation of this unserialize() bug was tricky, as vBulletin classes are not deserialisable. Discover the exploitation in our latest blogpost:
